Mining
Are you pouring your profit right back into the ground?
The typical heap leaching mining project loses hundreds of thousands of dollars in profits.
How? By precious minerals leaking back into the soil after being extracted. It’s a sad fact that leakage has become an accepted part of the industry — just a cost of doing business.
The good news is that it doesn’t have to be this way! It is possible to construct containment systems that don’t leak. As in ZERO LEAKS. How do we know? We’ve been on construction teams that have made it happen!
We view your project as you do, as an Income Producing Asset. And, we want to help you maximize your ROI. It begins with understanding what you might already be losing.
Daily Gold Concentrate Potentially Leaching Through Geomembrane
The table above shows potential loss for Gold concentrate, based on leakage considered to be at acceptable standard levels (ALR). For example, on a containment system that leaks 550 gallons per acre per day, there is a daily mineral loss of 0.10 t oz per acre.* Over a 10-year life span, that equates to a $47.5 million loss on a 100-acre asset!
Do you consider these leakage rates acceptable? We certainly do not! What a huge drain on your project’s ROI.
In almost all cases the cost of preventing these leaks is a very small fraction of the cost of losing concentrate.
*Assumes:
– Gold concentration of 1.5 ppm in pregnant leach solution
– Gold: $1,300 USD/t oz
And What About Copper?
The table Copper Concentrate Leakage shows the approximate mineral content that is potentially lost, on an acre-per-day basis, at the ALR rates for copper.
Assumes:
– Copper concentration of 5,500 ppm in pregnant leach solution
| Leakage Rate | Mineral Concentration / Day | Mineral Concentration / Year |
|---|---|---|
| 550 gal / acre / day | 25.2 lbs | 9,200 lbs |
| 250 gal / acre / day | 11.5 lbs | 4,182 lbs |
| 32 gal / acre / day | 1.5 lbs | 5481bs |
On time. Under budget. Compliant. (Without sacrificing quality.)
And, if extracting the ore was not challenging enough, today’s miners have to deal with increasingly difficult environmental and safety regulations while trying to keep public relations in check and still turning a profit.
We appreciate our miners; without you, life as we know it today would not be possible. After all if you can’t grow it, you have to mine it!
Mining is a big, hard and dangerous job and mine companies want to keep their employees and the environment safe and this is no small challenge. Often times, these challenges may have you searching for answers to questions such as:
- How do I maximize my heap leach ROI?
- How do I continue to meet stringent ALR regulations?
- Is Zero leak containment really possible?
- How do I ensure my surface operations won’t damage any sound containment system and create further delays or fines?
- How do we find people with the right expertise to get these projects built?
While we cannot change the regulations, we can partner with you to ensure that your containment projects are on time, under budget and compliant.

Avoid Costly Fines and Shutdowns
In your industry, time is money. Every minute counts.
You have millions of dollars invested in your assets. Your construction and maintenance costs alone are in the tens of thousands – per day.
With the regulatory changes that are coming, why go through a learning curve that someone else has already mastered? We’ve been doing Subtitle C and Subtitle D containment for 25 years.
We know what causes delays and how to avoid them. We know how to execute quality and do it swiftly. We can anticipates issues before they become your problem.
Let us help you get ahead of these impending changes. We have applied decades of construction quality experience and expertise in containment systems across multiple industries including waste, energy, agriculture and mining.
Can you afford a 30-day shutdown–especially one that could be easily prevented?
DESIGN
While the rule changes may be new to you, we are experienced in navigating clients through the strict requirements of Subtitle D and Subtitle C containment facilities. It all starts with proper design.
If your goal is an installation that lasts 30 years, how do you know your specs will deliver that?
If your installation needs to meet Subtitle D, how do you know what qualifies as compliant and what does not?
We will consult to ensure that the plans and specifications will meet your business goals while also ensuring quality installation and regulatory compliance.
IMPLEMENTATION
We are your eyes and ears on the jobsite. We ensure that you’ll have a sound installation that meets regulatory standards, is functionally operational and is constructed for the desired life of the asset.
We understand that time is money and you can’t afford to waste either. You need it done right the first time. You can’t afford to slow down. But, you also can’t afford an involuntary shutdown due to poor construction.
When we’re on your jobsite, you won’t find the wrong material being allowed on the project, failing welds and other shoddy workmanship. Not only do we address the major items, we’re sticklers about details. Poor beveling, extrusion overgrinds and mismatched welding rod should not be tolerated.
Using our CQA services, you’ll know that the construction goes according to the project specs.
OPERATIONS
You’ve invested millions in your project and it is now operational. The last thing you need is a sound liner system that becomes ruined after installation.
Does your staff know how to live and work on the geomembrane without damaging it? Did you know that the chemical used to clean a drilling rig will destroy a liner system within hours of contact? Do the vendors who empty your frac tanks know where they are allowed and now allowed to drive their vehicles?
You’ve just completed the construction of a pad and someone drives an ATV across the liner or drives a survey stake through the geomembrane, an instant and fineable breach of containment. We’ve seen it happen! It’s imperative that your staff understand how to protect your investment!
We will provide training for everyone onsite, from construction staff to your employees to vendors.
Here Is A Prime Example Of How We Protect Your Project:

How Are You Handling Subtitle D?
Right now, many companies in the energy industry are faced with numerous, ominous questions regarding new Subtitle D regulations:
- How do we meet the new compliance standards within what seems to be an unachievable timeframe?
- How do we develop the right strategy for becoming compliant?
- How do we write a proposal to the regulatory agencies that will result in the issuance of a permit?
- What materials do we need and will they be available within the timeframe I need them?
- How do we find people with the right expertise to get these projects built?
While Subtitle D may be new to your industry, it’s certainly not new to us.
We’ve been successfully navigating Subtitle D regulations for 25 years.
We understand that what you do is critical to the nation’s power grid and how having reliable power for everyone depends upon your installations being sound and compliant.We can’t change the rules or delay their implementation. But, we can partner with you to help you be successful during a very challenging time.
What makes this all the more challenging is that the actual field construction of containment systems is a niche specialty. It’s hard to internally staff personnel who are experts at it, yet you need someone who understands your business priorities and how those issues translate into your construction project and impact your bottom line. We understand that.
Change is coming. Let us help you manage it.
CONSULTING
Regulations, time and cost all dictate that your impoundment systems need to be completed on-time and under budget while meeting all regulatory compliance requirements.
Most battles are won and lost in the “War Room” before the troops ever hit the field. Containment Construction is no different.
Containment designs should be based on a fundamental understanding of field operations and processes. This will ensure a better quality project that can be constructed with a shorter timeline while meeting all regulatory requirements.
While designs are often focused on material functionality, we bring a field perspective to that process that is often missing: field constructability!
We are experts in ensuring your containment and capping systems meet the rugged demands of your business. Let us help you plan and execute your containment projects:
On-time, under budget, and Subtitle D compliant!
CONSTRUCTION SERVICES
Large scale energy projects require a construction manager. It’s the construction manager who watches over your project to ensure that the time and money you’ve invested in your design isn’t wasted in the field.
You need someone who can manage construction operations from a business goals perspective in light of new Subtitle D requirements.
Anything can look good on paper, but will it be constructed in a way that satisfies both you and the regulators?
As your construction manager and field team, start to finish we make sure your job is done right. We are a team of highly-skilled field professionals. Everything we do revolves around ensuring that your containment system will perform with outstanding quality throughout its intended life span.
Our founders started the company as experienced field managers driven to invest in field quality. We’re proud to say that CQA Solutions was “built by the field for the field.”
At the end of the day, you need a team that gives you the best ROI and protects your assets. That’s what we do.

Geosynthetics & Geotechnical
The quality of the final product is documented to greatly increase when a third party CQA is present.
Geosynthetics
Although geosynthetics can be installed without third-party CQA, the quality of the final product is documented to greatly increase when a third party CQA is present. This is particularly important when dealing with the geomembrane liners, which are typically installed as an impermeable barrier to keep components contained.

- Subgrade Preparation
- Installation CQA
- Field Destructive Seam Testing
- Documentation
- Panel Layout/As-built
- Report Preparation

Field Services
Simply put, the field technician is the eyes and ears of the certifying engineer and can make or break a project, possibly leading to catastrophic conditions in the future. To perform field testing at an acceptable level, the technician must understand the principals behind the tests, the intent of the design, the material characteristics, and be able to discern when the test numbers are not representative of the actual conditions they are observing in the field.
Too many technicians do not function beyond just recording the test data — they fail to make the correlation to what they are actually observing. One example of this is when a technician writes down a passing compaction test, yet fails to observe that the material has changed, or that the lift shows signs of bonding failure. Either of these scenarios jeopardizes the integrity of the clay liner and can lead to substantial problems in the future — problems that are unrecognized by the certifying engineer whose eyes and ears have failed him.
Applications
- Structural fill / Sub-base construction
- Compacted Clay Liners
- Subgrade Preparation
- Test Pads
Soils Methods
- Nuclear Densitometer
- Drive Cylinder
- Sand Cone
- Field Moisture
Sampling
The importance of obtaining representative samples of any construction material will result in increased efficiency during the construction process and help keep project costs within the anticipated budgets. Far too often, project delays in construction develop because the materials change was not noted, or were not sampled properly. We carefully monitor each sample source and test pit for any variances that could cause problems during construction.
Methods
- ASTM Standards
- Bulk Samples
- Shelby Tubes
- Split Spoon Sampling
Materials
- Soils
- Aggregate/Sand/Gravel
